I checked with Galfer, and they said they have no listing for the Rocket, and asked for measurements, to wit:
No rotors listed for this application by us. If you can send dimensions I can have our tech department double check, I would need the following info to check.
-OD
-ID
-Thickness
-Offset (if any)
-# mounting holes
-distance between 2 closest mounting holes

Anyone have this handy ?
